Spatio-temporal reasoning for multi-scale modeling in cardiology.

In this paper, we present an overview of the CARDIOLAB environment where the heart's electrical activity is modeled at distinct space and time scales. CARDIOLAB uses three models, two of which are based on cellular automata, and the third on qualitative simulation. They are combined around a blackboard for multi-scale quantitative and qualitative modeling of cardiac electrical activity. A general account on how spatio-temporal representation and reasoning methods are applied to produce heuristic associations is also presented.
